Microchip ATMEGA3250P-20AU: A High-Performance 8-Bit AVR Microcontroller Engineered for Robust Embedded Control
The Microchip ATMEGA3250P-20AU stands as a powerful embodiment of the proven AVR architecture, delivering a compelling blend of performance, integration, and reliability for complex embedded systems. This member of the ATmega family is specifically designed to handle demanding tasks across a wide array of applications, from industrial automation and automotive systems to advanced consumer electronics and sophisticated user interfaces.
At the heart of this microcontroller is a high-performance 8-bit AVR RISC processor core. Operating at speeds up to 20 MHz, it achieves a throughput of nearly 20 MIPS, enabling the device to execute powerful instructions in a single clock cycle. This efficiency allows designers to achieve a superior balance between processing power and low power consumption. The core is supported by an extensive 128 KB of in-system self-programmable Flash memory, providing ample space for even the most feature-rich application code. This is complemented by 4 KB of SRAM for efficient data handling and 4 KB of EEPROM for critical data storage that must be retained after power cycles.
A defining feature of the ATMEGA3250P-20AU is its exceptional peripheral integration, which minimizes external component count and reduces total system cost. It boasts a comprehensive set of communication interfaces, including four USARTs, two Master/Slave SPI serial interfaces, and a Two-wire Serial Interface (TWI) for I²C communication. This makes it ideal for systems requiring multi-node networking or communication with numerous sensors and peripherals.
For control-oriented applications, the microcontroller is equipped with a rich suite of timers and PWM channels. It features two 8-bit timers/counters and three 16-bit timers/counters, offering immense flexibility for waveform generation, precise timing, and motor control functions. Furthermore, it includes an 8-channel, 10-bit ADC for accurate analog signal acquisition from sensors. A unique and powerful capability is its built-in JTAG (IEEE 1149.1 compliant) interface, which provides not only advanced debugging and programming but also On-Chip Debug support, significantly accelerating the development and troubleshooting process.
Housed in a robust 64-pin TQFP package, the device offers a multitude of I/O lines for interfacing with the external world. It is engineered to operate over an extensive industrial temperature range, ensuring stable performance in harsh environments.
